Automating lead routing with serverless functions
Instantly route form submissions to the right inbox or CRM using lightweight serverless handlers.

Why automate routing
Fast responses convert better. Automating lead routing ensures every submission reaches the right person or system instantly—without someone triaging an inbox. With Astro’s static‑first approach, a small serverless function (or edge function) is enough to validate, enrich, and dispatch leads reliably.
What to implement
1) Validate and de‑spam
- Honeypot + timestamp checks to catch bots
- Schema validation for required fields (name, email, message)
- Rate limiting or IP throttling on bursty traffic
2) Enrich as needed
- Normalize country/region from phone or IP
- Tag source/medium from UTM params
- Append page context (pathname, referrer)
3) Route to the right destination
- Assignment rules (geo, product line, deal size)
- Primary destination: CRM (HubSpot, Pipedrive, Salesforce) via API
- Secondary notifications: email or Slack with context
- Fallback queue if primary API is down
4) Notify with context
- Include message excerpt and page URL
- Provide a one‑click link to reply or claim ownership
Observability and resilience
- Emit structured logs for received, validated, enriched, dispatched events
- Measure p95/p99 response time and end‑to‑end delivery time
- Use retries with backoff for third‑party APIs; dead‑letter on repeated failure
- Keep PII minimal; encrypt secrets; don’t log sensitive fields
Example flow
- Form POSTs JSON to
/api/contact
- Function validates + spam‑screens
- Enrichment adds UTM and page context
- Router decides owner/team and sends to CRM
- Slack/email confirmation includes a deep link to the CRM record
What you get
- Faster first response → higher conversion
- Clear ownership → fewer dropped leads
- Measurable pipeline from site to CRM → easier optimization
Conclusion
Automated routing turns every form submission into a tracked, owned, and quickly answered opportunity. Start small with validation and a single integration, then layer on enrichment and SLAs.
